 |*get sys performance stat*
 |Show real-time operational statistics: CPU load per CPU, memory usage, average network/session, uptime.
 
+|*diagnose sys top [_refresh_] [_num-of-processes_] [_iterations_]*
+|Print list of running processes updated every _refresh_ seconds (default 5), for
+_iterations_ times, sorted in descending order by the CPU load. This `top` command does not display all processes by
+default, to show them all, set _num-of-processes_ to high number, for example
+100. Press "m" to sort the processes by memory consumption. The displayed table
+is in this order: `Process id`, `process state: (R)unning, (S)leep, (Z)ombie,
+(D)isk Sleep, < Means higher priority`, `CPU used`, `Memory used`.
+
+|*dia sys kill _signal-id_ _process-id_*
+|Forcefully kill the process with the id of _process-id_, sending it the given _signal-id_ (Linux signals, e.g. 9, 11).
+
 |*diagnose debug crashlog read*
 | Display crash log. Records all daemons crashes and restarts. Some daemons are more critical than others.
 
 |*diagnose debug crashlog clear*
 | Clear the crash log.
 
+|*dia sys top-mem [_num-processes_] [detail]*
+|Show top (default 5) processes by memory usage, optionally set number of
+processes to show with _num-processes_, and use `detail` to get verbose output
+(a lot).
+
 |*get hardware memory*
 | Show memory statistics: free, cached, swap, shared
